'roor. Eon REMOVING TIRES.

Application filed November 13, 1920. Serial No. 423,880.

To all whom it may concern:

Be it known that JOHN J. OBRIEN, fa citizen of the United States, residing at Leesburg, in the county of Lake and btate of Florida, have invented certain new and useful Improvements in Tools for Removing Tires, of which the following is a specifica- My said invention relates to tools for collapsing and restoring split rims in the operationmf removing tires from and replacing them upon demountable rims and it consists in the construction and arrangement, of the tool and attaching devices whereby such work may be performed very quickly and by which the rim may be reassembled very quickly. The tool also embodies a number of"'other features which make it useful for various other purposes as a general automobile accessory, all as will be hereinafter more fully described and claimed.

Referring to the accompanying drawings, which are made a part hereof and on which similar reference characters indicate similar parts,

thereon, both of which parts are or maybeof any appropriate construction.

The rim A is divided as at point 10 and has a locking device 11 of a common type, or any appropriate type, one part of the rim having an overlapping tongue with a lug 12- adapted to engage with a perforation in the other part as is usual.

The tool comprises a central member or handle 15 longitudinally perforated, one end of the perforation being screw-tln'ea'ded, it is also transversely perforated the transverse perforation cutting through the longitudinal'perforation. A shoulder is formed at point 16 and a shankl'? with a head 18 on one end and an engaging hook 19 upon the other is mounted in said perforation. the head 18 being adapted to abut against shoulder 16. Another shank 20 with a screw- Figure 1 is aview partly in section and threaded section 21 is mounted in the screwthrcaded end of perforation in member 15 and is formed with an engaging hood 22 on its outer end similar to the hook 19 on the (inter end of shank 17. It will be noted that the outer facesof such hook-shaped ends are slightly curved. This is to pro vide tor a tree rocking movement between the engaging parts during operation andavoid all binding or strain.

Engaging plates 23 and 24. are secured to the inner face of the rim A, plate 23 being secured at a point near to the split 10 in the r m and plate 24 at a point a considerable distance away from and on the opposite side of said split. Said plates 23 and 24 are duplicates, the construction being shown most clearly in Figure 4. It will be noted that they are formed with a cut-out portion .in one edge, the lips of which are tapered toward each other, that is, the recess is of a dove-tailed form and open at one side.

As is well understood, the locking device 11 for securing the two ends of the rim together causes a projection on the interior surface of the rim A and lugs 25 of corresponding thickness are positioned on the interior of said rim at intervals to support it uniformly on the felloe of the wheel. The plates 23 and 24 are made of corresponding thickness and thus lay in the space between the wheel fcllocs (indicated by dotted line in itself having an enlarged end in which a rectangular socket 27 is formed to adapt the same to be used as a wrench and its other end 28 is formed as a screw-driver or prying tool. A tongue 29 is formed on one side of said handle 26 adapted to engage with a groove in the side of the perforation in the member .15 to lock the handle from rotary motion therein. If desired a series of such handles formed as wrenches may be pro-' vided, thus providing .a wrench for different sized nuts. It will be understood that in the use of the device as a wrench either shank 17 or 20 may be used as a handle to secure additional leverage.

the wellknown manner; the plates 23 and 24 are then exposed; the hooks l9 and 22 are then'adjusted in the recess of plates 23 stantially in an inward direction tending to slide said end along the end of the other part to open joint 10, or until it is free from and 24 and member'lo is turned to contract the tool or shorten the connection between said plates as indicated by the arrows in dotted lines. Plate 23 being attached close to joint 10 the strain upon the end of the rim-to which plate 23 is attached is subthe adjacent end of said rim, when two parts will slide into an overlapped position, as

shown in Figure 6 enabling the tire to bereadily removed. After a tire has been adjusted on the rim, by reversing the motion of member 15 the end of the rim-bearing plate 23 is forced out-ward, as indicated b the arrow in wholeilines, and as soon. as it reaches the position where the ends will pass each other it snaps into place, when the locking plate 11 may again be engaged and the rim be in condition to be replaced on the wheel. I

By this means atire may be removed very quickly and the rim may beirestored to its closed position very quickly after a tire has been placed thereon.

A' tool is also pro vided which is very useful formany other purposes and desirable to have in the tool box of an automobile and one that when dissembled occupies but little space.

Having thus fully described my said vention, what I claim as new and desirevto secure by Letters Patent, is:

1.- A tool for collapsing split rims comprising a member having intersecting longitudinaland transverse perforations, a portion of said lon itudinal perforation being threaded, a shan threaded at its inner end for engagement with the said threaded portion of the longitudinal perforation and having its outer end formed with a notched portion for engagement with a rim, a second shank carried by the said member having its outer end formed similar to that of the first said shank and a handle'adapted to be inserted in the transverse perforation, said handle adapted to serve as an abutment tor the said second shank, Isubstan; ially. as set of plates for securing to a rim, each plate having a recess entering from one edge and wider at one face of the plate than at the other, in combination witha pair of rods and means for moving them' toward and fromeach other, the outer ends of said rods being shaped to form heads insertable laterally in the said recesses and interlocking with said plates, substantially as set forth.

4'. Rim operating means comprising apair of plates for securing to a rim, each plate having a recess entering from one edge, in combination with a pair of rods and means for moving them :toward and from. each other, the outer ends of said rods being shaped to form headsinsertable latefallyj in the said recesses and interlocl ring with said plates, substantially as set forth.

5; Rim operating means comprising plates for securing to a rim, providing a recess on each side of the break in the rim in combination with a pairof rods and means for moving them toward and from each other, the outer ends of said rods being shaped -to forms heads insertable laterally in the said recesses and interlocking with said plates, substantially asset forth.

In witness whereof Ehave hereunto set my hand and seal at W'ashiiig'ton, District of Columbia, this 12th day "on November, A. D. nineteen hundred and twenty. v
